The Roof Pitch calculator computes the pitch of a roof based on the rise (r) and the run (R).  RoofPitch.png                             Gabled Roof 

INSTRUCTIONS: Choose your preferred units and enter the following:

  • (r) rise:This is the measure from the base of the gable to the apex of the roof (see diagram).
  • (R) run:This is the measure from edge of the roof to the mid-point or highest point of the roof (see diagram)

Pitch:  The calculator computes the angle of the pitch in degrees and the approximate rise over run (e.g. 4/12)
